M4500-48XF8C Reset Password
How can I reset my login password when unable to log in

Hi Netbridge-Brian ,
I am very sorry about that... Are you using telnet/ssh? We might very well need serial/USB connection for it to work.
Do you have Serial RJ45 RS232 adapter handy? If so, please connect it to the console port, and use a DB9 to USB RS232 adapter to connect to your PC (so that you get a COM port to use in your TeraTerm or Putty.
If not, please reach out to ProAVDesign@netgear.com (just send us an email with a link to this thread) and one of our SEs will come back to you shortly.
Thank you, Laurent

Hi Netbridge-Brian ,
Did you backup your configuration? The method below is deleting the startup config to return in factory-default mode:
- Start the switch normally, then once you are prompted to "User:" press "ctrl+z". This will take you to the M4500 Menu
- When prompted with "Enter your menu option:", enter "b"
- Type "sudo bash"
- Type "qnos-mgmt -c" and confirm (this will clear the saved startup config)
- Type "exit" to exit bash, then "exit" again, this takes you back to the M4500 menu
- reboot the switch by typing "4"
- Switch is now on default configuration, with user admin and no password, you will then be prompted to enter a new password
Please let us know!
Regards, Laurent

Hi Laurent
I tried this method, but after I type "b" and press enter, it only returns me to the M4500 menu, or pressing q during startup does not enter any mode. Is there any other way?
